Plus - and admittedly I'm sketchy on this - when they talk about "space" expanding, it seems like what they really mean is "the extent of matter" expanding.

No, it's really the space expanding.

"No, it's really the space expanding."

So, space is a "thing"? A "grid" of sorts?

Michelson & Morely would NOT be pleased...

"No, it's really the space expanding."

That raisins in taffy theory of physics doesn't explain why "inflation" stopped (or slowed), much less why the universe is still expanding at ever-faster rates, much less why different laws of physics existed back then (e.g. accelerating large masses vastly faster than the speed of light C).

Which is to say, it's a bunch of hooey.
